This invention relates to a tool for applying a binding strip to the ede of a panel and more particularly to a too for app ying a channelshaped rubber binding strip to the edge of a glass window panel for anautomobile body, and has for its principal object the provlsion of atool by means of which the binding strip may be quickly and firmlysecured upon the edge of the panel and which at the same time willprotect the hands of the operator from injury due to contact with sharpportions of the panel edge.

It is a further object to provide a tool of the character described thatis light in weight and so formed as to fit comfortably into the h handsof the operator so that it will not produce discomfort or undue fatigue.

It is also an object of the invention to provide a device of thecharacter described that is simple in construction, easy and economicalto manufacture, and which will not readily get out of order in use.

Other objects and advantages will appear as the description proceeds.

In the accompanying drawings, there is illustrated one mechanicalembodiment of the device of the invention per se, and also an embodimentshowing a strip cutting and stapling device attached to the tool. Thedrawings, however, are to be taken as illustrative only and the scope ofthe invention is to be limited solely by the scope of the subjoinedclaims.

In the drawings:

Figure 4 is a sectional view on the line 44 of Figure 3.

Figure 5 is a perspective view of a short section of the bindingmaterial which this devicle is adapted to apply to the edge of a paneFigure 6 is a top plan view of a somewhat modified form of the device ofthe invention showing a strip cutting device and a stapling device aplied thereto.

Figure is an elevational view of the modifiedsform of the deviceillustrated in Figure Referring to the drawings in detail, Figure 1illustrates the ap lication of the device of the invention. In thisfigure, the numeral 10 generally indicates a panel such as a glasswindow panel for a vehicle body. The numeral 12 generally indicates astri of binding material usually formed of ru her, which is applied tothe edge of the glass panel to form a protective covering for the sharp,rough edges of the panel, and also to provide a weatherbead for the anelwhen the panel is mounted in a vehicle ody to prevent water from passinginto the body between the panel and its su port.

The form of this rubber inding is particularly illustrated in Figure 5,and comprises a channel shaped member having a web portion 13 and twoflange portions 14 and 15 enclosing a slot which is adapted to receivethe edge of the glass panel. It will be noted that the free edges of theflange portions 14 and 15 are closer to ether than the portions of theflanges WlllCh are attached to the web 13, thus making it necessary tospread the flange portions apart before thelstrip can be pressed u n thepanel. This operation has formerly en done en-v tirely by hand, thepanel 10 bein placed upon a bench B and inserted in t e guide G Theflange members were then separated by the forefingers of the operatorand the binding forced upon the edge of the panel with the thumbs. Asthe binding was placed upon the panel, it was stretched by the operatorand the panel turned to different positions until the binding had beenplaced entirely around it. The over-lapping portion of the binding wasthen cut. off and a staple driven into the binding to hold the endstogether.

That part of the o eration which comprises inserting the bin ing uponthe ed of the panel was found to be slow and t one and also a fruitfulsource of minor injuries ticularly dangerous, they would cause theoperators on this particular operation to lose a considerable amount oftime, thereby rendering the operation more expensive than it should be,as well as causing a considerable amount of discomfort to the operators.The device which forms the subject matter of this invention was designedto obviate this condition.

Referring to Figure 2, the numeral 18 indicates a tubular handle portionformed of sheet metal. This handle portion is provided along one sidethereof with a guard member 19, the form of which is illustrated insection in Figure 4.

i From an inspection of Figure 4, it will be seen that the guard membercomprises a rolled upper portion 20, and a straight depending portion 21having a small bead 22 formed upon the lower end thereof. This guardmember 19 may be formed integrally with the handle portion 18 or may beformed separately and secured thereto by any suitable means such aswelding, soldering, or by rivets or screws.

Within the tubular handle 18, there is a spreader member 24 secured tothe bottom portion of the handle by means of the screws 25. Referring toFigure 3, it will be observed that this spreader member 24 comprises astraight shank or securing portion 27 provided with screw threadedapertures for the screws 25, and an upturned, wedge shaped, portion 28which projects upwardly into the tubular handle portion and is designedto pass between the flange portions 14 and 15 of thevbinding strip 12 toseparate these flange portions as particularly illustrated in Figure 4.

From an inspection of Figure 2, it will be observed that forwardly ofthe inner edge of the upturned portion 28 of the member 24, the bottomportion of the tubular handle member 18 is cut away leaving a pair ofspaced side members 30 and 31 in the forward end of which a rollermember 33 is mounted upon a shaft 34 which projects through suitableapertures in the side members 30 and 31. Beyond the apertures the sidemembers 30 and 31 are bent backwardly upon themselves and are thenflared out so 7 that the side member 30 forms a fingerrest 35 and theside member 31 forms a thumb rest 36. The backwardly bent portions ofthe side members 30 and 31 also serve to retain the shaft 34 in theapertures provided for it in the side members. Washer members 38 and 39are placed between the ends of the roller and the side members 30 and31.

From a further inspection of Figure 2, it

will also be observed that the end of the tubular handle portion 18opposite the roller 33 is flared out at 40 and that the portion of thehandle member surrounding the spreader 24 is bulged out at 41 to allow asufiicient opening in the top of the handle member to start the bindingstrip over the spreader 24 and under the roller 33.

The. operation of the device is as follows:

. The rubber binding strip 12 is threaded through the tubular handle 18as illustrated panel as illustrated in Figure 1. The tool is then drawnaround the edge of the panel, the spreader 24 separating the flanges 14and 15 so that they pass easily over the edges of the glass and theroller 33 forcing the binding strip firmly down upon the panel.

After a certain amount of the strip has been applied to the panel, thetool is moved away from the panel and the operator grasps the bindingstrip immediately in front of the tool with his right. hand, at the sametime holding the opposite end of the strip upon the panel with his lefthand, and stretches the binding strip upon the panel. binding strip hasbeen applied entirely around the panel, the over-lapping end of thestrip is cut off and the two ends of the strip are forced flushtogether. A metal staple is then driven through the strip straddling theat 46, and by means of the screws 47 a stapling device generallyindicated by the numeral 48. Referring particularly to Figure 7, thestrip cutting device comprises a bracket 50 having secured to one edgethereof a slide 51, and a stem 52 having at the upper end thereof a knob53 is mounted upon the slide 51 and carries at the lower end thereof aclamp 54 in which is secured the upper portion of a knife blade 55. Thestem 52 is urged upwardly by means of a compression spring, notillustrated, to normally retain the knifeblade 55 above the bindingstrip l2. Pressure on the knob 53 however,"'will force the stem 52 downupon the guide 51 and will force the knife blade 54 through the bindingstrip 12 When the Ill to cut the binding strip to the proper length.

The stapling device 48 is mounted upon the side of the tool andcomprises a bracket member supporting a guide 61 which in turn supportsa stem 62 upon which'is a'knob 63. Below the bracket 60 1s a staplemagazine 65 which holds a clip of staples which are spring pres-zedupwardly for the stapling device. The stem 62 is normally urged awayfrom the tool by means of a compressionv spring or other suitable devicebut pressure upon the knob 63 will force the stem 62 toward the tool andcause a staple to be inserted into the adjacent ends of the bindingstrip. As the specificstructure of a stapling device of this characteris old and well known, it is believed that a further description isunnecessary for the purpose of this disclosure.

In the operation of the modified form of the device, the binding stripis applied to the pgnel as described above. When the strip has enapplied entirely around the panel, the rear end portion of the tool israised,-the knob 53 is depressed to cut off the raised up end of thebinding strip. The two ends of the binding strip are then forceddirectly together and the knob 63 is depressed to secure the endstogether by means of a metal sta 10.
